Organotin compound as inhibitor of digestive enzymes of gastrimargus transverses and oxya velox

ABSTRACT

In the present investigation it was observed that the injection of each concentration of TPTA into the haemocoel of Gastrimargus transverses and Oxya velox caused greater inhibition in the activity of both the enzymes. The trend of inhibition in the activity of both the enzyme [amylase and invertase] was progressive from lower to higher concentration as well as related with time following injection. In G. transverses, the injection of different concentratons produced more inhibition in the activity of amylase than invertase, whereas in O. velox invertase activity was inhibited more than that of amylase. The highest inhibition was recorded by 0.1% concentration at 48 hours following injection i.e. 64%, 63% and 56 and 52% repectively for invertase and amylase in G. transverses and O. velox
